I can't seem to trigger PendSV
Hi, I have created this kernel for an ARM Cortex M3, on an Atmel (microchip) board, and now I am porting it to Nucleo f767zi.I thought it would be an easier task, just adapting the HAL calls, and kernel (C and ASM) routines would keep the same. But I...
STM32U585 memory mapped hyperRAM and STOP2
I'm using a STM32U585 that has some hyperRAM attached to OSPI2. I've memory mapped it and it's working well during normal operation. I've noticed, though, that when I leave it powered and put the processor into Stop 2 mode, it corrupts some of the ...
Resolved! About VREFBUF Characteristics, Degraded Mode
I would like to know the lower limit of the voltage at which the ADC can maintain accuracy, but I don't know the next mode.What are the degradation modes of VREFBUF characteristics in the STM32G031x4/x6/x8 data sheet?Also, what are the conditions for...
Resolved! typo in STM32H5 NUCLEO144 user manual
In UM3115 STM32H5 Nucleo-144 board (MB1404) rev 2 - August 2023, page 29, table 19 listing CN13 pinout, A7 D- USB_FS_N STM32H5 Pin is typed as PB11. I guess it is a typo, it should be PA11. In the same table, B7 D- USB_FS_N is correctly typed as PA11...
STM32H743 Clock to pdm microphone is not changing
Hello,I'm just started using a nucleo-h743x. I have configured the I2S to acquire some audio from the a digital microphone.Supposing that I use one of SPI1,2,3 for that, the i2s clock reaching the peripheral should the one that in MX is called (To SP...
Current in mA in STOP1 mode
I've implemented STOP 1 mode on STM32L476 using HAL function. The current consumption is >1mA even in STOP mode while I've disabled all the clocks. I'm unable to understand this.
Resolved! Issue while setting pins as Analog to save power
Hello everyone, I'm trying to set all the pins(except 11) of port F of STM32L476 as Analog to save power. for(uint8_t GPIO_PIN = 0; GPIO_PIN < 16; GPIO_PIN++) { if(GPIO_PIN != 11) GPIOF->MODER |= (3 << (GPIO_PIN * 2)); } But it resets my progr...
USB composite (HID & CDC)
I am trying to use the usb COMPOSITE library. (AL94.I-Cube-USBD-COMPOSITE.1.0.3)Followed the instruction How to generate the code from MXcude for USB CDC and USB HID.the code compile successfully. and I can see those devices when I attach my NUCLEO b...
Nucleo STM32L432KC - Issue using PB4 as I2C3
Hi All,I am looking to use the I2C3 for connecting to an OLED display. I have already used I2C1, and due to design requirements, I cannot use the same bus to communicate to the OLED display, and hence I2C3 is my only option. I2C3_SDA is an alternate ...
Resolved! STM32L4 Series: Using DMA to copy from Flash to SRAM
Hi there,Looking into the TRM for the STM32L412xx board, I was wondering if I could use a DMA to copy constant data from the Flash to SRAM. The system architecture block diagram connects the DMAs to Flash through the DCode path:However, while reading...
